Almost all of the above is configurable at compile time!
So if you don't need one or more features, just leave
them out at configure time =) ... Only O(1), rmap15b, AIO,
epoll,dcache fastwalk and vservers are static additions!

All unstable / very experimental patches have been
removed from this edition They will be available in the
Workstation Edition of wolk4.0w.

Lots, _really_ lots of code fixes and cleanups were also made.

Although this is named Server Edition it is also perfectly
suitable for your desktop and for sure for all of your
servers. It's stable, fast, rock solid and very secure.
